点一下不认识的单词。

Salin-de-Giraud is a major center for salt production in southern France. It is located on the right bank of the Rhone River. Every year, about one million tons of salt are made here by evaporating seawater.

In addition to salt, sodium carbonate is recovered at Salin-de-Giraud. This chemical is important for making Marseille soap. The area of the salt ponds shown in the image is about 14.7 by 18.3 kilometers.

The image was taken on September 2, 2020. It was captured by ASTER, a special instrument on the Terra satellite. ASTER has 14 spectral bands and can see from visible light to thermal infrared. It has a high resolution, from 15 to 90 meters.

ASTER helps scientists study many changes on Earth. It can monitor glaciers, active volcanoes, crop health, wetlands, and coral reefs. It also measures surface temperatures and heat balance on soils and rocks.

The U.S. science team that works with ASTER is at NASA’s Jet Propulsion Laboratory in California. ASTER was built by Japan’s Ministry of Economy, Trade and Industry. The Terra mission is part of NASA’s Science Mission Directorate in Washington.

难句解析

  1. 1

    In addition to salt, sodium carbonate is recovered at Salin-de-Giraud.

    难点在于短语“In addition to salt”，意思是“除了盐之外”。整句意思是：在萨兰-德-吉罗除了生产盐，还回收碳酸钠。

  2. 2

    The U.S. science team that works with ASTER is at NASA’s Jet Propulsion Laboratory in California.

    难点在于定语从句“that works with ASTER”，修饰“science team”，意思是“与 ASTER 合作的美国科学团队”。整句：与 ASTER 合作的美国科学团队在加州的 NASA 喷气推进实验室。

  3. 3

    The Terra mission is part of NASA’s Science Mission Directorate in Washington.

    难点在于“is part of”，意思是“属于……的一部分”。整句：Terra 任务属于华盛顿 NASA 科学任务理事会的一部分。
